I haven’t used that combo on a full suss, but it’s been absoulutely 100% on the hardtail- better than the MRP chain device and E13 Guidering it replaced. Chaingrowth could make things trickier- more chain slack essentially.

Guys, im looking to find a way to run 1×10 on the other half`s marin bouncer without a chain guide. Currently using a cheese superstar guide and need something more reliable. The design of the frame doesn’t help, its this one http://www.marin.co.uk/2008/bikedetail.php?ModNo=3824.

Thick/thin and clutch mech will do it. I went the expensive way and did XX1 but no looking back now. I run no guide and no dropped chain in a good few hundred off road miles. With my old 2×9 and MRP guide I used to lose the chain fairly frequently, so happy to report thick/thing and clutch mech do definitely work.

I did the Trans Savoie race with a thick thin and clutch mech. (Got a few strange looks from fellow racers) Dropped the chain once on a farm track for no apparent reason.
Rode the alps for another 2 weeks without dropping. Only time I have had an issue was in some deep sticky mud which seemed to be sticking between the links. Don’t know if a chain guide would have solved it or not? HTH
